Hsie,

>After modify my McIDAS setup following your instructions.  I only get April
>10, 18Z ETA data.

Please send me a listing of the versions of RTMODELS.CFG, NOGRIB.CFG, and
GRIBDEC.CFG that are being used by your XCD grid data monitor, DMGRID.

For the copy of RTMODELS.CFG on our machine that is running XCD

SCRATCH=5001
ETA=  1 5011 120000 240000 480000
MRF=  1 5101 120000 240000 960000
MAPS= 0 5201 30000
MDR=  2 5301
AVN=  3 5401 120000 240000 720000
NGM=  3 5501 120000 240000 480000


And with the following ADDE dataset definition for RTGRIDS/ETA (in RESOLV.SRV):

N1=RTGRIDS,N2=ETA,TYPE=GRID,RT=Y,K=GRID,R1=5011,R2=5070,C=ETA Grids,

I get the following listing for my ETA grids:

Note that the uncommented entries are the grids to NOT decode.

The only change that I made to GRIBDEC.CFG is to set the MAXGRD= parameter
to 4000; it was 2000.  I have received information from SSEC recommending
that this parameter be set to 5000:

MAXGRID=5000              # maximum number of grids to store in a grid file

There is something mysterious going on with the ETA decoding in XCD.
UVa is having problems getting any ETA grids to decode, AND they are
only able to decode MSL grids for MRF!
